The prevalence of long Covid symptoms and Covid-19 complications (plus updated estimates)

‘The UK’s Office of National Statistics (ONS) published data regarding the prevalence of symptoms associated with “long COVID” in patients who recovered from acute SARS-CoV-2 infection. The data indicate that approximately 20% of infected individuals exhibit symptoms for 5 weeks or longer, and 10% report symptoms for 12 weeks or longer. This corresponds to an estimated 186,000 individuals in England with symptoms lasting between 5 and 12 weeks. The findings are based on responses to the UK’s COVID-19 Infection Survey, which utilizes a nationally representative sample from across the UK, and efforts are ongoing to gather additional data, including on symptoms that persist longer than 12 weeks. A more detailed look at the available data shows that prevalence of long COVID symptoms* tends to increase with age, peaking in the 35-49 years (26.8%) and 50-69 years (26.1%) age groups, compared to the 2-11 years (12.9%) and 12-16 years (14.5%) age groups. Additionally, there appears to be a statistically significant increase in prevalence among women (23.6%) compared to men (20.7%).’
